Do you know the express PCB difinition?

what is express PCB?
Jim thinks this question may have two different meanings.
One means is an express PCB company.
And the second means is the design software for PCB manufacturing.

If this question is asked by new PCB guys.
The answer is the first situation.
Because most China PCB supplies have express PCB agency.
And most orders the PCB manufacturers may require customers use their express PCB agency.
So the new PCB guys want to learn the express PCB agency information.

The second situation is a PCB designer asking this question.
Printed circuit board produces process is very complex.
And the PC board design software has many types.

In fact the express PCB is one of the PCB designing program.
So the second situation answer is design software.
